AC Power Supply in Junos Space Appliances
This topic applies to the following Junos Space Appliances: JA1500 and JA2500.
A Junos Space Appliance ships with a single AC power supply module, shown in Figure 4. An additional AC power supply module can be installed to provide redundancy.
While it is possible to provide redundancy in the Junos Space Appliance using a combination of AC and DC power supply modules, we recommend that you do not provide redundancy in this manner. Instead, use two AC power supply modules or two DC power supply modules if you want to provide redundancy.
Table 10 shows details of the AC power supply module for a Junos Space Appliance.
